مرشح ZWO OIII 7 نانومتر - 31 ملم - OIII7nmD31

Finally an OIII filter that doesn't soak up all the detail in my nebulae. The 7nm bandpass cut through the light pollution in my backyard without killing contrast.

The 7nm bandwidth really cuts through the light pollution here, making the Veil Nebula pop even from my Bortle 6 backyard. Mounted it on my 31mm nosepiece and used it with my ASI camera; the stars stayed tight all night. Worth every penny for the detail it pulls out.

Finally got this 31mm OIII filter dialed in on my setup, and the 7nm bandwidth really cuts through light pollution better than my old 12nm did. The contrast on the Veil Nebula was noticeably sharper in just a single night of integration.
